health π€§ H1N1 cases up in Delhi; here's the flu vs COVID lowdown π·
H1N1 influenza cases have sharply increased in Delhi, reporting 1,777 infections by August 20, 2026, up from 229 last year. Cities like Bengaluru and Kolkata are also seeing surges, but ICMR confirms no new strain is circulating. Both H1N1 and COVID-19 are respiratory infections with similar symptoms like fever and cough. Testing is necessary because treatments and underlying viruses are different, and symptoms alone aren't enough for diagnosis.
